Parsley tea for inducing period

So both of my period apps told me I was supposed to start my period next week on the 13 of feb ( my period apps are almost always accurate). I didn't want to have my period for Valentines day for several reasons so I looked online about how to induce your period, trying to make it come a few days earlier so it won't be here for valentines day. Two ways I saw online was to make parsley tea and drink it throughout the day and one was two intake a lot of vitamin C (pills or through drinks) I did both from feb 1 - feb 6 ( projected period start date feb 13) and my period came today on the 8th!
